Justin,
That is a great site. Thanks!
And thanks for the postfix entries below.
I just assembled the computer yesterday and have postfix
running. I'll work through the other things this week and hope
to have the system complete (other stuff besides email) by
next weekend.

I built it firstly on Ubuntu 9.04 Server 64 bit but when I migrated to
purpose built machine I used 32bit server. Server does not install GUI
so on the second build I completed the initial bare bones OS
installation, sorted SSH server and Webmin. From then on I did all the
rest of the install from my workstation, browser open at workaround.org
for guidance, SSH and Webmin for installing and tweaking.

To get what you want you will need Webmail and POP/IMAP. There are a few
options, all of which have their fan base, but I haven't yet gone wrong
with Dovecot and Squirrelmail. My 15 client users are way more than
happy with the setup, especially the huge reduction of spam hitting
their mailboxes. I am also some what more responsive than the local ISPs
to sort issues.
